               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

The Pension Committee
CSX Corporation Capital Builder Plan
CSX Corporation
Richmond, Virginia

We have audited the accompanying statements of net assets available for benefits
of the CSX Corporation Capital Builder Plan (the Plan) as of December 31, 2001
and 2000, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2001. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2001 and 2000, and the changes in its net assets available for
benefits for the year ended December 31, 2001, in conformity with accounting
principles generally accepted in the United States.

NOTE 1 - DESCRIPTION OF THE PLAN

The following description of the CSX Corporation Capital Builder Plan (the Plan)
provides only general information. Members should refer to the Summary Plan
Description and the Plan document for a more complete description of the Plan's
provisions.

General: The Plan is a defined contribution plan covering certain union
employees of CSX Corporation (CSX) and affiliated companies (collectively, the
Company or Plan Sponsor). During 2001, the Internal Revenue Service confirmed
the Plan is an Employee Stock Ownership Plan (ESOP) and is designed to comply
with Section 4975(e)(7) of the Internal Revenue Code of 1986, as amended (Code)
and is subject to the provisions of the Employee Retirement Income Security Act
of 1974 (ERISA), as amended. The designation of the Plan as an ESOP had no
material impact on the Plan provisions except as noted below.

Contributions: Each year, members may contribute, in 1% multiples, up to 15% of
annual compensation, as defined by the Plan. Certain eligible members may also
contribute other compensatory awards to the Plan. Subject to certain
limitations, members may reinvest distributions received from another qualified
plan. Members may revise investment direction of their contributions daily.
After December 31, 2001, a member may defer up to 50% of his or her eligible
compensation instead of 15%.

The Company contributes a specified number of shares of CSX common stock on an
annual basis to certain member accounts of the eligible groups, as defined by
the Plan. These shares may be purchased throughout the year and are held by CSX
Corporation in a rabbi trust until they are contributed to the Plan and credited
to the members' accounts.

The Plan also provides for a Company matching contribution of stock or cash to
certain eligible members. The amount and timing of the Company contributions
varies according to individual agreements. All Company contributions are
invested in CSX common stock, except for certain contributions which can be
directed by certain eligible groups as defined by the Plan.

NOTE 1 - DESCRIPTION OF THE PLAN, Continued

Member Accounts: Each member's account is credited with the member's
contributions and allocations of (a) the Company's contributions and (b) Plan
earnings, and is charged with an allocation of administrative expenses.
Allocations are based on member earnings or account balances, as defined.
Forfeited balances of terminated members' nonvested accounts are allocated to
active members' accounts. The benefit to which a member is entitled is the
benefit that can be provided from the member's account.

Vesting: Members are immediately vested in their contributions plus actual
earnings thereon. Members are immediately vested in Company matching
contributions made in cash and are vested after five years of credited service
in Company matching contributions made in stock (ESOP.) A member is immediately
vested upon death, disability or retirement. Effective January 1, 2002, all
accounts under the Plan are fully vested.

Loans: Members may borrow from their fund account in amounts equal to no more
than the lesser of $50,000 in an aggregate amount of all loans from the Plan or
50% of their vested account balance. Members may not borrow from an ESOP account
or the Company match account even though those accounts are used in the
calculation to determine the amount available for the loan. Loan terms range
from one to five years unless the loan is to be used in conjunction with the
purchase of a primary residence. The loans are secured by the balance in the
member's account and bear interest at the prime rate in effect at the beginning
of the quarter in which the loan originated. Principal and interest are paid
ratably through payroll deductions.

Payment of Benefits: Upon termination of service, a member may receive a
lump-sum amount equal to the vested value of his or her account, or upon
disability or retirement, elect to receive monthly installments over a 240-month
period. Surviving spouses of retired or disabled members may elect to continue
monthly installments or to initiate monthly installments. A member with an
account balance of $5,000 or less shall be paid in lump sum.

NOTE 1 - DESCRIPTION OF THE PLAN, Continued

Plan Termination: Although it has not expressed any intent to do so, the Company
has the right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA. In the event of Plan
termination, members will become 100% vested in their accounts.

Administrative Expenses: The administrative expenses of the Plan are paid by the
Company or from Plan funds as the Plan Sponsor directs. All of the
administrative expenses of the Plan during the year ended December 31, 2001 were
paid from Plan funds.

Diversification: Investment diversification is offered to participants close to
retirement so that they may have the opportunity to move part of the value of
their investment in Company stock into investments which are more diversified.
Members who are at least age 55 may elect to diversify their company match
contributions or ESOP allocation. Effective January 1, 2002 members who are at
least 50 years old may elect to diversify their accounts. Effective May 31, 2002
all restrictions were removed and members may diversify their accounts
immediately.

Dividends: Dividends paid on shares of Company stock held in a member's account
are reinvested in shares of Company stock. Effective January 1, 2001, a member
or spousal beneficiary may elect to have dividends paid to them in cash. Any
change in an election will apply only to ex-dividend dates occurring after the
date such election is received. A member who does not make a timely election
will have the dividends paid to their account and reinvested in shares of
Company stock.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation: The financial statements have been prepared under the
accrual method of accounting in accordance with accounting principles generally
accepted in the United States.

Use of Estimates: The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

NOTE 3 - INVESTMENT IN MASTER TRUST

Investments in CSX Common Stock (stated at fair value) are valued at the last
reported sales price on the last business day of the year. Investments in mutual
funds are measured by quoted market prices and are reported at aggregate fair
value at year-end. Synthetic guaranteed investment contracts are reported at
fair value, which in the case of such contracts approximates contract value.
Member loans are valued at their outstanding balances, which approximates fair
value.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are recorded on the
ex-dividend date.

At December 31, 2001, the Plan's interest in the net assets of the Master Trust
was approximately 31%.
